How to Display Information About Processes

  1. Obtain the process ID of the process that you want to display more information about.
    # pgrep process

    The process ID is displayed in the first column of the output.

  2. Display the process information.
    # /usr/bin/pcommand PID
    pcommand

    The process command that you want to run. For a description of all the process commands, see Figure 4, Table 4, Process Commands (/proc).

    PID

    Identifies the process ID.

The following example shows how to use process commands to display more information about a cron process.

# pgrep cron Obtains the process ID for the cron process
4780
# pwdx 4780 Displays the current working directory for the cron process
4780:   /var/spool/cron/atjobs
# ptree 4780 Displays the process tree that contains the cron process
4780  /usr/sbin/cron
# pfiles 4780 Displays fstat and fcntl information
4780:   /usr/sbin/cron
